Foraging strategires: generalists and specialists -- what are they? What are some examples? Why are they considered generalists or specialists?
When is it good to be a generalist and when is it good to be a specialist? What kind of environments would be best for either?
How can the evolution of a new foraging trait affect the success of a foraging strategy?
Quiz:
Quiz 9 (10 points) The Fizbak is back. It is a bird that only eats worms. It lives in an environment with lots of other specialist worm-eating birds. Each worm, on the other hand, has different behaviors that make it unique. With this in mind: 1. Should the Fizbak be a specialist or a generalist? (1 points) 2. Thinking about competition or adaptations, explain why you chose your answer for #1? (3 points) 3. A Rolkog is an organism that hunts snails at night using their eyes. An example of a foraging adaptation is: (1 points) a) a mutation that allows Rolkogs to reproduce faster at night b) immunity to poison from a cobra snake c) better sight at night d) the ability to better smell fruit 4. Define a population (3 points) and give an example (1 point). 5. There are 3 individuals in a population in the year 1999. Next year in 2000 there are 6 individuals. In 2001 there are 12 individuals. In 2002 there are 24, in 2003 there are 30, and in 2004 there are 33, and in 2005 there are 35. What kind of growth curve is this? (1 point) It might be helpful to make a plot of time vs. individuals. a) exponential growth curve b) parental care growth curve c) logistic growth curve d) non-growth curve
